' OE BOONE, IOWA.

IMPROVEMENT IN COMBINED GAUGES AND TRV-SQUARES.

Specification forming part of Letters Patent No. 116,805, dated July 11,1871.

To all whom it may concern:

Beit known that I, FREDERIC CASTLE, of Montana, in the county of Booneand State of Iowa, have invented a new and useful Improvement inCombined Gauges and Try-Squares; and I do declare that the following isa true and accurate description thereof', reference being had to theaccompanying drawing and to the letters of reference marked thereon, andbeing a part of this specification, in whichw Figure l is a perspectiveof my device, in use, looking from the front. Fig. 2 is a similar view,looking from the rear.

Like letters refer to like parts in each iigure.

The nature of this invention relates to an improved construction of animplement for gangin the length of weather-boards in siding a house, andwhich will sustain in its proper position the board being gauged, and ismore especially designed as an improvement upon a device for a similarpurpose as secured to me by Letters Patent issued to me on the 21st dayof March, 1,871.

The invention consists in the construction and arrangement of certainset-screws, by means of which the apparatus is made to vary to iitdifierent thicknesses of casings, as more fully hereinafter described.

In the accomjintnying drawing, A represents the stock ofthe clamp,provided with a shoulder, a', the thickness of the lower edge of aweatherboard. B a stud, projecting' laterally from the stock, just belowthe shoulder a. C are two thin metallic dogs, one of them being securedto the rear face of the stock, and projecting` above the shoulder a,while the other is secured to the rear face of the stud B, and projectsabove it, both said dogs being upon the same plane. D is a lever,journaled in a mortise in the stock, near its lower end, and to it issecured the sharpened dog E in such a manner that closing the lever ontothe stock will compel the dog forcibly to project through the mortise inthe stock, and a reverse motion of the lever will withdraw the dog. The

corner boards of the frame and the two lower courses ofweather-boardsbein gin place, the stock is secured to the building1 by inserting thetwo dogs C under the lap of the upper board, the stud B being brought upagainst the corner board. The lever is then closed in on the stock, whenthe dog E is forced into the board opposite the mortise, thereby holdingthe stock firmly in place. F is another stud, of the same length as thestud B, projecting laterally from the bracket G, in the same direction,the former being upon the plane of the front of the stock, while thelatter slides on the rear face of the same. G is a bracket, adjustablysecured to the upper part of the face of the stock by a set-screw, b,passing through a slot, c, in the stock. This bracket supports the boardto be gauged, and determines its lap over the one in position, and thismay be varied by moving the bracket up or down, as desired. H is asquare, whose short arm is slotted, as shown in Fig. l, and isadjustably secured to the stud l" by a set-screw, d, passing throughsaid slot into the stud, so that the square may be moved laterally orinclined to the right or left. I J Iare set-screws, the former passingthrough the stud B near its outer end, and the latter, in' like manner,passing through the bracket G nea-r its upper end, in order to compelthe device to t different thicknesses of casings.

There should be two of these devices, alike in every particular, exceptthat the one for the opposite end of the'siding should have its studsproject in the opposite direction 5 or, in .other words, they should bein pairs, one right-hand and the other left.

In practice, it is found that the device secured in the manner describedin the Letters Patent hereinbefore referred to will rock and not be heldfirmly while in operation, and that it will not work efficiently withdiiierent thicknesses of casings. This rocking and inefficiency areavoidedin the device now presented.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the stud B, bracket Cr, and set-screws I and J,constructed and arranged substantially as and for the purposes setforth.

FREDERIC CASTLE. Vitnesses:
